The number of computed tomography examinations have increased in Sweden and the rest of the world, which has increased the radiation dose to the patients. Increased number of examinations gives greater potential risks to the population. If the examinations with computed tomography continues to increase it may result in a future public health problem, because the risk of radiation induced cancer. The aim of this study was to view if the increased number of examinations with computed tomography can be justified considering the risk of radiation-induced cancer and the balance between risk and benefit. Approximately 20% of the examinations performed in Sweden today are not justified. Fundamental principals in radiology is to be able to plan, implement and evaluate the examinations regarding to radiation dose, radiation safety and image quality. In this systematic literaturereview, 14 scientific articles have been quality examined, analyzed and compiled to a result. Even though computed tomography is a useful tool in a diagnostic purpose, this study shows that there is a potential risk for radiation-induced cancer after exposure to ionizing radiation in computed tomography examinations. Justification is an recurrent and important part when taking decision if a examination should be performed or if another diagnostic option could be considered. At every institution that works with ionizing radiation there has to be a person that holds the radiological management role. That person shall have the overall responsibility to make sure that an assessment of the justification is made.
